New KX1 #1424

[Uli DF5SF]

Hello,

now finished assembling my KX1 with KXB8030.

Problem:
I have a test oscillator on 10109 kc.
BFO = 00, RIT = OFF
After adjusting DDS (-49) I read 9.00 and receive this signal as
a 620Hz tone.
But my transmit frequency is 10108.5 kc.
Is this normal or what to do ?

Uli,

There is another menu item for calibration of the DDS (transmit frequency). The BFO just calibrates the received frequency display. I don't recall where it is in the menu, take a look at the assembly manual, the final alignment instructions, and look for the DDS adjustment.

Mike,
many thanks for your answer.
Your right, first calibrate the BFO for display accuracy and then
the DDS.
There is a dependency between the BFO and DDS settings.

Now I have the following on all 4 bands:

display accuracy  +- 100 Hz
difference RX/TX frequency  +- 50Hz
